' y linPnovliivnzn'lr IN BASE-BURNING eroi/Es.

Be it known that we, IsnauL Samana' and PETER 0. GARRETT, of Cedar-Rapids', in thecounty of Linn and State of Iowa, have invented anew and useful Improvementin ABase-Burnin'g Stoves; and we do hereby declare that the following is a full, clear, and

exact' description thereof', which will enable others skilled in the art tov lmake' and use the same, reference being had to thc'accompanying drawing forining a part of this specification.l y

This invention relates to improvements lin vbaseburning stoves, and consists in making thcjirc-pot open at the sides, from the grate up to the bottom of the reservoir with which it is connected.

The said open fire-pot being' used, and the draught being arrangedto canse the llame and calorieeurrentsto impinge against the outer shell ot' the cylin der, as low down and as4 directly as possible; the

`-said arrangement provides a space between the. cylinder and the fire-pot to the bottom-'ofthe'stovm for heating purposes. 'v 'f AThe invention also comprises as npply-magalzine, above the reservoir, which may be filled andcovered, and then opened at the bottom to discharge'the coal into the reservoir-.in a way to avoid the escapeof The invention also-comprises the application of -certain inside plates, for usewheu burning hard eoal,

whereby the saine is more ciiiciently done,.the said plates being removed `when burning soft coal, in which case'they are notreqnired.

Figure LL is'a sectional elevation 'of o ur improved stove when arranged for burning hard coal;

Figure 2 is a sectional elevation in a plane perpendicular "tothat' of f ig. 1,and .when adjusted ,for soft coal; and f l Figure 3 is a horizontal section of lthe same, taken on the line of iig. l.

Similar letters of reference indicate corresponding parts. v

Instead ot using the close `sided'briclrflined Iii-epots now commonly used, we propose -to make the same open at the sides, as shown at e, and" we arrange the reservoir cylinders B to fit on the tops of the pots, as shown, so that the caloric eurrent s will vpass through the openings directly: against the ontside cylinders D, and as low down as 'possiblele also make this arrangementt,\ continue the heating space inside thc case I) to thel bottom of the stove. Y

Belowl the fire-pot, for its support, and fo',I p roviding an air space E to supply the air to .the llOtOm of the grate, is a plate, F, resting on the bott-cnil Q, midlng'lgidcwrhwitlrvholcs H, to allow part of the R11' to vpass-into the heating space between the pot A and the cylinders D. The bottom grate I may be arranged for shaking and.v dumping in the ordinary way.

Air to support combustion, and also to supply the space between the cylinders to feed the gases, may

be admitted through the tube IC to the space E below the ire,'a part of which passes up through the passages H. L I

lVe propose `to `employ spiral or other shaped anges, or guiding plates L, between the cylinders B and D, for directing the product of combustion around in the space in its upward course, in a way to cause the most direct contact thereof with the outside shell to cause the greatest radiation ot' heat.

'Ihe reservoir is provided witha (over, M, below the top of the stove, and above this and below the covcr is a magazine, having a drop door, O, at the bottom, and a cover, I, at the top. l y

The door O is closed by an eccentric-wheel, Q, under it, on a shaft, It, passing through thc side o't' the stove, forturning by hand.

- This bottom door, being kept closed, will prevent the escape of any gases or smoke when the cover l is taken off. to pnt in coal; and the cover P being put, on previous to opening, the door O will prevent the escape of gas then, so that the tire may be supplied without theescape of gas or smoke, as in other I rIhe slide door S is employed to open a direct escape, to be used for starting the fires.

For burning hard coal we'employ the two concave 4plates .'I- U, above the tire-potffor contracting the supply of coal, and limiting it so 'that there will be a clear space under the platel and above the coal around the top of the grate, which we find to facilitate thesbnrning of the hard coal; but for soft coal, which burns more freely, these plates are not 'required.- These plates may be cast either in sections or in one piece, as may be found most convenient.'

By the employmentof this cylinder B and tirepot A, we may readily convert any cylinder stove into a base-burner, and other .base-burners may also 'be supplied with these cylinders and pots.
